Reflex Winkelmann GmbH–part of the Building+Industry division–is a leading provider of high-quality heating and hot-water supply technology systems. Under its Reflex brand, the company, which has its headquarters in Ahlen in the German region of Westphalia, develops, produces and sells not only diaphragm expansion vessels, but also innovative components and holistic solutions for pressure maintenance, make-up, degassing and water treatment, storage water heaters and plate heat exchangers, as well as hydraulic manifold and vessel components. Reflex Winkelmann GmbH has over 1,500 employees worldwide, giving it an international presence in all major markets.

Gas pockets in water heating/cooling systems can impair their functionality to the extent that entire components and systems can break down completely. They reduce energy transmission efficiency and create resistance and the risk of corrosion. Corrosion encourages the formation of dirt and sludge in heating and cooling circuits which, in turn, can result in further impairment of the entire system.

There are a number of factors that contribute to the smooth running of a heating and cooling system. Air, micro-bubbles, dirt and sludge, for example, can have a significant detrimental effect on functional reliability as they reduce energy transmission efficiency and create the risk of corrosion.

Correct pressure ratios are a basic precondition for correct functioning of heating, solar and cooling water systems and pressure booster systems. Like all other substances, the volume of water changes with its temperature. Unlike other liquids, water does not expand proportionately to the temperature.

The Longtherm heat exchangers can be adapted to almost any required profile. They are available in a wide range of sizes, embossings and connection types, offering the best compromise between low flow resistance and highly efficient heat exchange. This allows Longtherm heat exchangers to cover all major energy applications.
